In addition, the embodiments and features of the embodiments of the present application may be combined with each other without conflict.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
In an LED light grouping synchronization system, as shown in fig. 1 and fig. 2, the LED light grouping synchronization system includes a server 10, a plurality of synchronization terminals 20, a plurality of switches 30, a plurality of controllers 41, and LED light bars 50, the server 10 is in communication connection with the plurality of synchronization terminals 20, each synchronization terminal 20 is in communication connection with one switch 30, the plurality of controllers 41 form a controller group 40, each switch 30 is in communication connection with the plurality of controller groups 40, each controller 41 is in communication connection with the plurality of LED light bars 50, and all the LED light bars 50 are arranged in a preset shape.
In the present application, the controller 41 is divided into a plurality of controller groups 40, and the picture of the image frame is divided into grouped picture operation data corresponding to each controller group; to the corresponding controller packet 40. Thus, each controller 41 only needs to receive and process the data of the controller group 40 to which it belongs, thereby greatly reducing the data amount to be transmitted and processed, and reducing the time required for data transmission and processing, even if the area controlled by the synchronization terminal 20 is large, the LED light bars are large, and the tape load is large, the delay problem caused by data transmission and processing can be avoided, and it can be effectively ensured that all the LED light bars 50 controlled by the synchronization terminal 20 synchronously display the pictures of the same frame.
As shown in fig. 3, an embodiment of the present application provides an LED light packet synchronization method for synchronizing data transmission control between a terminal and a controller, including:
s100, acquiring controller grouping data and a lighting arrangement diagram.
The controller grouping data includes at least the number of the controller groups 40, and the correspondence between each controller group 40 and the controller 41. The lighting map may include the connection relationship between the controller 41 and the LED light bar 50, and may further include the position of the LED light bar 50 in a preset shape. The lighting pattern may correspond to all the LED light bars 50, or may correspond to only the LED light bars 50 connected and controlled by the synchronization terminal 20. Based on the controller grouping data and the lighting map, the picture area corresponding to each controller grouping 40 can be determined to facilitate the subsequent segmentation operation.
The controller packet data and lighting map may be stored on the server 10 or on the sync terminal 20. Accordingly, the sync terminal 20 may obtain the controller packet data and the lighting pattern from the server 10 or its own memory.
S300, image frames are obtained, and according to the controller grouping data and the lighting arrangement diagram, the image work data of the image frames are divided to obtain grouping image work data packets corresponding to the controller grouping.
The image frames refer to the pictures belonging to the corresponding areas of the LED light bars 50 controlled by the synchronization terminal 20. The image frame may be a single frame or may include multiple frames.
According to the light distribution map, the image working data of each pixel point on the LED light bar 50 corresponding to the image frame, that is, the image working data of the image frame, can be calculated. Then, according to the controller grouping data and the light distribution map, determining a corresponding area of each controller grouping, namely the corresponding LED light bar 50, and segmenting the image working data of the image frame by using the position of the corresponding LED light bar to obtain a grouping image working data packet corresponding to each controller grouping.
The image frames may be acquired from the server 10 in real time by the synchronization terminal 20, and then the synchronization terminal 20 performs step S300 in real time each time one image frame is acquired. It will be appreciated that the synchronization terminal 20 may also not acquire image frames from the server 10 in real time. For example, the sync terminal 20 may receive and store a plurality of image frames in advance. The synchronous terminal 20 reads the image frame at the corresponding time according to the time requirement, and executes step S300.
It is understood that, when the synchronization terminal 20 receives and stores the image frame in advance, the division of the screen operation data of the image frame may be performed when the image frame is received, so as to obtain the grouped screen operation data corresponding to each controller, and store the grouped screen operation data. The synchronous terminal 20 reads the grouped picture working data corresponding to each controller group at the corresponding time according to the time requirement, and packs the grouped picture working data packet corresponding to each controller group for subsequent transmission.
And S500, transmitting each group picture working data packet to a corresponding controller group.
After obtaining the packet screen work packets corresponding to the respective controller packets, the sync terminal 20 sends out the packet screen work packets in a request or multicast manner. The transmission may specifically be in an ethernet on demand manner.
Specifically, the sync terminal 20 may pack each group of frame work packets into UDP packets, so as to implement data transmission through ethernet. The UDP packet may include data of the packet screen work packet and address data of the controller packet 40. The address data of the controller packet 40 may be an IP address, a MAC address, or the like for addressing. The UDP packet may further include address data, a port number, a channel number, and the like of the controller 41, so as to help the controller 41 to quickly obtain data corresponding to itself from the packet.
Specifically, the sync terminal 20 packetizes each packet screen work packet into a UDP packet, and transmits the UDP data to the switch 30. The switch 30 records the address data of each controller packet 40, and after receiving the UDP data packet, the switch 30 obtains the address data from the UDP data packet, i.e., the address data can be transmitted to the corresponding controller packet 40 in a point-to-point manner by using an ethernet on demand or multicast manner, instead of the prior art, the data transmission is performed in a broadcast manner. Each controller 41 only needs to receive and process the data of the controller group 40 to which it belongs, so that compared with the existing method of broadcasting and sending the data of all controllers, the data size of a single data packet is greatly reduced, the time for each controller 41 to receive and process the data is reduced, and the problems of frame delay and asynchronism caused by the fact that the controller 41 receives and processes the data with large data size are avoided.
In the LED light grouping synchronization method provided in this embodiment, by dividing the image frames according to the controller grouping, each controller 41 only needs to receive and process the data of the controller grouping 40 to which it belongs, compared with the existing method of sending the data of all controllers by broadcasting, the data size of a single data packet is greatly reduced, the time for each controller 41 to receive and process the data is reduced, the problems of frame delay and asynchronization caused by the large data size received and processed by the controller 41 are avoided, and it can be effectively ensured that the LED light bars 50 controlled by all the synchronization terminals 20 synchronously display the pictures of the same frame.
In some embodiments, the image frames are not acquired from the server 10 in real time, as shown in fig. 4, step S300 may specifically include:
s310, image data and playing time parameters are obtained, wherein the image data comprises a plurality of image frames.
The picture data refers to the picture content of the corresponding area of the LED light bar 50 controlled by the synchronization terminal 20 in the picture, and may include a plurality of image frames. The playing time parameter mainly includes a playing period, and may further include a frame rate and other control parameters.
The synchronous terminal 20 can directly obtain the picture data and the playing time parameter from the server 10. At this time, the server 10 may divide the entire program file to obtain the picture data corresponding to each of the sync terminals 20. The complete program file contains the picture data of all the sync terminals 20 and is the complete picture content of the whole area.
In addition to the division of the program file by the server 10, the synchronization terminal 20 may divide the program file by itself to obtain screen data belonging to itself. At this time, the synchronization terminal 20 acquires the complete program file from the server 10, and divides the complete program file according to the lighting map to obtain the picture data of the terminal.
The division of the complete program file by the synchronization terminal 20 may also be performed without the aid of a lighting map. A sync terminal 20 capable of acquiring the complete program file and the region data of the sync terminal 20 from the server 10; the synchronous terminal 20 intercepts the corresponding picture data from the complete program file according to the region data. In this case, the program file does not need to be divided according to the lighting map.
And S320, calculating the picture working data mapped to each pixel point according to each frame of image frame and the lighting map.
After the synchronization terminal 20 acquires the image frame, the data mapped to each pixel point may be determined according to the lighting map. Because every pixel actually comprises LED lamp pearl, consequently, can also further convert the required work data of LED lamp pearl work into. The working data of all the pixel points of the LED light bar controlled by each synchronization terminal 20 form the image working data of each image frame.
It can be understood that each pixel point can be composed of a single-color LED lamp bead, and also can be composed of three or more LED lamp beads.
S330, according to the local time and the playing time parameter, a playing time table corresponding to each frame of image frame is calculated.
The synchronous terminal 20 can calculate the playing time table of each image frame, i.e. the specific and accurate playing time of each image frame, according to the local time and the playing time parameter. The play schedule may then be associated with the picture-work data for each image frame and then stored in memory so that it can be read directly at the time of actual play without recalculation.
S340, according to the playing timetable, at a preset time, reading the picture working data of the image frame corresponding to the time, and according to the light distribution diagram and the controller grouping data, dividing the picture working data to obtain a grouping picture working data packet corresponding to each controller grouping.
According to the play schedule, the synchronous terminal 20 reads the image working data of the image frame at the corresponding time when the time is preset. Meanwhile, the synchronization terminal 20 obtains controller grouping data and a lighting map, divides the image work data of the image frame, and packs the image work data to obtain a grouping image work data packet corresponding to each controller grouping.
In order to improve the execution efficiency of step S340, the synchronization terminal 20 may read the picture working data of several image frames from the memory in advance according to the play schedule, and store the picture working data in the buffer. The buffer can be a Cache memory or a buffer on the memory. In this way, by caching the data in advance, the time for the central processing unit of the synchronous terminal 20 to read the data from the memory device is reduced, and especially when a large amount of data is processed, the delay influence of the time consumed by reading the data on the subsequent transmission can be reduced.
The method comprises the steps of obtaining picture frames in advance to generate a play time table, then dividing the picture frames according to the play time table, and sending grouped picture working data packets corresponding to all controllers. The data is sent based on the play schedule, so that the sending time of the picture data of each frame can be effectively ensured to be basically the same, and further, the synchronous display of the pictures of the same frame by the LED light bars 50 controlled by all the synchronous terminals 20 is ensured.
In some embodiments, as shown in fig. 7, step S300 may specifically include:
s301, image data and playing time parameters are obtained, wherein the image data comprises a plurality of image frames.
S302, calculating grouped picture working data corresponding to each controller group according to each frame of image frame, the lighting layout and the controller group data, wherein the grouped picture working data is composed of picture working data corresponding to pixel points of the controller group.
Unlike the previous embodiment in which the dividing operation is performed only during the playing process in step S300, in the present embodiment, when the image frame is received, the dividing operation is performed according to the lighting map and the controller grouping data, so as to obtain the grouping picture operation data corresponding to each controller grouping.
S303, according to the local time and the playing time parameter, a playing time table corresponding to each frame of image frame is calculated.
S301, S303 are the same as S310, S330 in the previous embodiment.
S304, reading the grouped working data of the grouped pictures corresponding to each controller at a preset time according to the playing time table, and packaging the working data into a grouped working data packet of the grouped pictures.
And during playing, reading the grouped working data of the grouped pictures corresponding to each controller at a preset time according to a playing time table, packaging the working data into a working data packet of the grouped pictures, and then sending the working data packet.
By segmenting in advance, the data processing amount of the synchronization terminal 20 during playing can be reduced, and the delay influence of the time consumed by the synchronization terminal 20 for processing data during playing on subsequent transmission can be reduced.
In order to further ensure that the play schedules on all the synchronization terminals 20 are consistent, as shown in fig. 5, the LED light packet synchronization method may further include:
and S010, synchronizing the local time.
The local time may be synchronized by one of GPS time synchronization, network time service, or time synchronization based on a mobile communication base station. Preferably, the synchronization terminal 20 synchronizes the local time by using a time synchronization method based on a mobile communication base station.
And synchronizing the local time, and finishing before calculating the playing time schedule. By synchronizing the local time, it is possible to ensure time synchronization of all the synchronization terminals 20, and to ensure that the playing schedules calculated therefrom are the same.
Controller packet data may be stored at the sync terminal 20. The controller packet data may be fixed or dynamically adjusted. In some embodiments, the controller packet data, pre-configured, is fixed.
In other embodiments, the controller packet data may be automatically determined. Specifically, as shown in fig. 6, the LED light grouping synchronization method further includes:
s020: and carrying out packet training on the controller to determine controller packet data.
After the connection is established between the controller 41, the switch 30 and the sync terminal 20, the controller may be packet trained to automatically determine controller packet data.
Specifically, an initial number of packet groups may be set, and then all of the controllers 41 may be divided into a plurality of controller groups using the initial number of packet groups, and the number of packets may be equal to the initial number of packet groups. Then, the image frame may be transmitted from the sync terminal 20 to each controller group 40 with the image frame and the frame rate for the test, and the transmission time of all the controller groups may be acquired. And determining standard sending time according to the frame rate, and counting the sending timeout proportion of all the controller packets. And if the sending overtime ratio does not meet the preset requirement, gradually increasing the number of the grouping number, and repeating the previous test process until the sending overtime ratio meets the preset requirement. In this way, the number of the controller groups 40 and the correspondence between each controller group 40 and the controller 41 can be obtained, and the controller group data can be composed.
It is understood that S020 can also be utilized to obtain multiple sets of controller grouping data for reference in user configuration.
In some embodiments, the synchronization terminal 20 may further obtain a data transmission time, and dynamically adjust the controller packet data according to the data transmission time. Specifically, after step S500, the data transmission time of all the controller packets at the preset time is obtained, the transmission timeout proportion is analyzed, if the data transmission time exceeds the preset standard, the number of the packets can be correspondingly increased, the controller packets are subdivided to obtain new controller packet data, and the new controller packet data is adopted for processing at a subsequent time. It will be appreciated that the condition for triggering the controller packet data adjustment to reduce the amount of computation may be that the transmission timeout rate exceeds a predetermined criterion for a certain period of time, rather than just a single time determination.
In the LED light grouping synchronization method provided in this embodiment, by dividing the image frames according to the controller grouping, each controller 41 only needs to receive and process the data of the controller grouping 40 to which it belongs, compared with the existing method of sending the data of all controllers by broadcasting, the data size of a single data packet is greatly reduced, the time for each controller 41 to receive and process the data is reduced, the problems of frame delay and asynchronization caused by the large data size received and processed by the controller 41 are avoided, and it can be effectively ensured that the LED light bars 50 controlled by all the synchronization terminals 20 synchronously display the pictures of the same frame.
